- furic-acid vapors produced are eliminated in a condensed liquidcondition as quickly as possible. Assuming that .to a certain chambersystem morefl sulfurous acid is supplied than can be possibly worked up,the sulfurous acid is indeed uidized into sulfuric acid; but the lattercannot perfectly come into condensation within the chamber. This resultsin a dilution of the Gay-Lussac acid and in the interruption of thechamber process. Now one has already tried to overcome these drawbacksby providing condensers behind or between the chambers and by supplyingdiluted sulfuric acid or water in the direction opposite or transverselyto the flow of the gases, whereby one limited, however, the mutualaction simply tothe contact of the two'substances during their straightpassage through the condenser'in which one inserted sometimes the'knownresistances. Now in order to increase the effeet of such condensationsthe-present invention provides means by which the method hereindescribed is accomplished, this method effecting an intii'nate mixtureof the gases and condensing medium as well as a perfect elimination ofliquid and other undesirable ingredients, such as dust particles and thelike, The gases leaving the first chamber are before entering the secondchamber led through a lead turret, the walls of which are filled with,coke, and there set into a vivid whirling action, so that the gasparticles are,together with'steam, thrown against the coke walls, whichare irrigated with diluted sulfuric acid or water from the top of theturret and compelled to press themselves against each other as well asagainst'thedamp coke, whereby a very effective condensationof the acidvapor and through the medium of the irrigating acid or water a quickelimination from the whichmay have entered the chamber.

gas mixture of the sulfuric acid produced is obtained. a The uncondensedparticles of the difierent gases travel upward within the coke, wherebythey are further mixed and deprived from their eondensable substances.

The steam is not supplied directly to the chamber, but to the leadturret insuch a manner'that it is led through a paddle-tun 5*,

bine placed in the turret, the turbine being set in motion by thereaction of the steam, so that a very vigorous whirling actionon the gasparticles and the steam is obtained.

. The greater the supply of gas the more steam must be introduced, andthe'more cffectively works the turbine, and vice versa,

so that want of steam and rotary speed coincide with each other. In thisway the supply to steam is regulated according to the quality of the sulactly as is the process. Between the second and third chamber, third andfourth chamber, and so on similar turrets are provided.

The chambers can of course be entirely uric acid produced, ex-

dispensed with and. the gases led directly from one turret into theother. a

To put the method into practice, the following apparatus is employed: Alead turret of about eighty inches diameter is mount-. ed between thechambers in such'a manner that its bottom is placed about twenty casewith the normal chamber.

inches higher than the bottom of the chambers. The turret is at itsinner walls fittedwith a layer of coke ofabout twenty inches thickness,so that in the interior of the turret a s ace of about forty inchesdiameter is left. fnstead of with coke the turret may be fitted withperforated rin -plates.

The gases are led into t 1e lower part of the s ace left in the middleof the turret, while they are allowed to escape at the upper part of theturret.

A turbine with paddles is inserted in the middle space of the turret,while the hollow axle of the turbinecpassing beyond-the turret is closedup against the top of the turret by a water seal.

In the accompanying drawings, Figure 1 shows by way of example, invertical central section, one suitable constructional form of one of theintermediary turrets, while Fig. 2 is a horizontalsection on the line AB of Fig. 1.
